Offload bearing in a wireless communication system

Abstract

Apparatuses, methods, and systems are disclosed for offload bearing. One apparatus includes a processor that determines whether the apparatus will apply traffic steering rules for routing data traffic on a first route across a first access network and a second route across a second access network. In some embodiments, the first and second routes may be different. In various embodiments, the apparatus includes a transmitter that transmits information that indicates whether the apparatus will apply the traffic steering rules.

AI Technical Summary

Benefits of technology

The patent describes an apparatus and method for offload bearing, which involves determining whether to apply traffic steering rules for routing data traffic on different routes across different access networks. The apparatus can transmit information indicating whether it will apply the traffic steering rules, and can also receive information from external devices such as an ANDSF and a PCRF. The technical effect of this patent is to improve the efficiency of data traffic routing and offload bearing in wireless communication networks.

Problems solved by technology

Radio-level solutions for LTE-WLAN interworking and high-level solutions for LTE-WLAN interworking may not be coordinated.

Accordingly, the radio-level solutions and high-level solutions may be applied independently and simultaneously, resulting in traffic routing conflicts.

Such steering conflicts may be more severe in roaming scenarios in which the PGW resides in a H-PLMN and the eNB resides in a V-PLMN.
